Atomic Symmetry Groups, being continuous groups, are just a fallout of the Lie Groups and Lie Algebras. Atoms are structurally simpler than molecules but atomic symmetry is more complex than molecular symmetry. In quantum mechanics we study atoms first and then the molecules. In symmetry studies, we do just the reverse. In this book, apart from theories, the description of both the symmetry groups - atomic and molecular, are attended with adequate applications. Please note: Taylor & Francis does not sell or distribute the Hardback in India, Pakistan, Nepal, Bhutan, Bangladesh and Sri Lanka.

Chemistry is often seen as a difficult subject to understand. This book focusses on the triangle model that Alex H. Johnstone developed in the early 1980s. Originally conceived in the context of making chemistry more accessible to a wider range of learners, the model has been applied in almost every area of education in chemistry at all stages of learning. In looking at why chemistry is difficult, there are two central questions. Firstly, does the problem relate to the nature of chemistry and, secondly, does it relate to the way humans gain understanding? Both were found to be important and the answers to the two question were found to be connected. The triangle model arose from sustained research into human learning. The central finding from research is the critical role of working memory and the model rationalises so much evidence from chemistry education research as well as the repeated experiences of teachers of chemistry at all levels. In order to understand chemistry, it is essential to develop sound mental models of molecular reality. It generates major implications for the way a chemistry curriculum should be constructed and the processes of teaching and learning in chemistry when the goal is focussed on understanding the key ideas. Some of these implications are developed and pointers offered to more successful ways forward. The power of the Johnstone Triangle lies in the way it offers clear directions for all involved in chemistry education. It is hoped that this book will prove helpful to all involved in sharing the exciting story of the way humans have come to understand the molecular world, one of the great examples of great human endeavour.

This book is a marked departure from typical introductory geochemistry books available: It provides a simple, straightforward, applied, and down-to-earth no-nonsense introduction to geochemistry. It is for the undergraduate students who are introduced to the subject for the first time, but also for practicing geologists who do not need the heavy-duty theory, but some clear, simple, and useful practical tips and pointers. This book, written from the point of view of a practicing geologist, introduces the fundamental and most relevant principles of geochemistry, explaining them whenever possible in plain terms. Crucially, this textbook covers - in a single volume! - practical and useful topics that other introductory geochemistry books ignore, such as sampling and sample treatment, analytical geochemistry, data treatment and geostatistics, classification and discrimination diagrams, geochemical exploration, and environmental geochemistry. The main strengths of this book are the breadth of useful and practical topics, the straightforward and approachable way in which it is written, the numerous real-world and specific geological examples, and the exercises and review questions (using real-world data and providing on-line answers). It is therefore easily understood by the beginner geochemist or any geologist who desires to use geochemistry in their daily work.

Residues offers readers a new approach for conceptualizing the environmental impacts of chemicals production, consumption, disposal, and regulation. Environmental protection regimes tend to be highly segmented according to place, media, substance, and effect; academic scholarship often reflects this same segmented approach. Yet, in chemical substances we encounter phenomena that are at once voluminous and miniscule, singular and ubiquitous, regulated yet unruly. Inspired by recent studies of materiality and infrastructures, we introduce "residual materialism" as a framework for attending to the socio-material properties of chemicals and their world-making powers. Tracking residues through time, space, and understanding helps us see how the past has been built into our present chemical environments and future-oriented regulatory systems, why contaminants seem to always evade control, and why the Anthropocene is as inextricably harnessed to the synthesis of carbon into new molecules as it is driven by carbon's combustion.

"One smart book...delving deep into the history and implications of a daily act that dare not speak its name."--Newsweek Bodily waste is common to all and as natural as breathing. We prefer not to talk about it, but we should--even those of us who take care of our business in pristine, sanitary conditions. Disease spread by bodily waste kills more people worldwide every year than any other single cause of death. Even in the United States, nearly two million people have no access to an indoor toilet, while the sewers of major cities worldwide are an infrastructure disaster waiting to happen. With razor-sharp wit and crusading urgency, mixing levity with gravity, Rose George's The Big Necessity breaks the silence, turning the taboo subject into a cause with the most serious of consequences.

Marie Curie's story has fascinated and inspired young readersdecades. The poor Polish girl who worked eight years to be ableto afford to attend the Sorbonne in Paris became one of themost important scientists of her day, winning not one but twoNobel Prizes. Her life is a fascinating one, filled with hard work,humanitarianism, and tragedy. Her work with her husband,Pierre - the study of radioactivity and the discovery of theelements radium and polonium - changed science forever. Butshe is less well known for her selfless efforts during World Warto establish mobile X-ray units so that wounded French soldierscould get better care faster. When she stood to profit greatlyfrom her scientific work, she chose not to, making her methodsand findings known and available to all of science. As a result,this famous woman spent most of her life in need of money,often to buy the very elements she discovered.Marie Curie's life and work are given a fresh telling, one thatalso explores the larger picture of the effects of radium in worldculture, and its exploitation and sad misuse.
